About this study
Official title: 3D Visulization The Area Of Maximal Compression And Quantitative Assessment Stroke Volume And Ejection Fraction After Adjusting CPR Location
Use Transesophageal ultrasound in OHCA patients to identify the proper compression location
Read the detailed description
For patients with cardiac arrest, high-quality cardiopulmonary resuscitation is performed according to critical care management and Advanced Cardiac Life Support (ACLS). Rapid with powerful chest compression should be performed to maintain the heart's output and blood flow. An advanced airway should be established and adjust resuscitation based on collected clinical information. Transesophageal ultrasound examination is performed after the advanced airway is established without affecting the resuscitation. The investigators use the built-in ultrasound software (Philips QLAB 3D quantification advance, Philips Healthcare, USA, speckle tracking echocardiography (STE,Speckle tracking echocardiography)) to analyze stroke volume and cardiac output. The investigators collect the stroke volume and cardiac output at the chest compression position recommended by ACLS, as well as the stroke volume and cardiac output after adjusting the optimal chest compression position. The investigators expect it can increase the return of spontaneous circulation rate, survival rate, and neurological prognosis over time.

Questions about this trial
What is this clinical trial studying?
A study testing adjustment of CPR location in people with Cardiac Arrest (CA), run by National Taiwan University Hospital at 2 sites in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: enrolling by invitation, as of the sponsor's last update on 19 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
stroke volume, ejection fraction, end-diastolic volume, and end-systolic volume (time frame: 2 mins). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07017075, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Nov 2025; AzTrials last refreshed its copy on 27 Oct 2026.
